Attending:

• Connie Houchens (GSFC/ACD)
• Sharon Orsborne (GSFC/ACD)
• Bob Hartman (GSFC/ACD)
• Byron Leas (NRL/CAL)
• Jim Ampe (NRL/CAL)
• Luca Baldini (INFN Pisa/TKR)
• Mike Huffer (SLAC/ELX)
• Larry Wai (SLAC/I&T-IFCT)
• Ric Claus (SLAC/I&T-Online), minutes author

Topics:

• Core (Ric)
• Progress was made with HippoDraw. We expect to be able to release it soon.
• ELX (Mike)
• Nine tower architecture 2a test stands delivered
• All existing tower test stands have been upgraded
• Action item for CAL: Report to Mike when second unit should be delivered
• Action item for TKR: Report to Mike the test stand distribution plan for Pisa and UCSC
• ACD has new pseudo-AEM firmware installed
• Connie and Sharon are progressing as well as before the upgrade
• New engineer at SLAC (Oren Milgrome, MILGROME@SLAC.STANFORD.EDU) has obtained a new version GAFE tester and is using it with the Online system to build test scripts
• Action item for ACD: Find out where GAFE testers for Online and FSW are
• Still expecting test jigs to come out of fabrication this week.
• Discussion on high rate event data taking:
• Flight hardware will not have any power-on reset capability
• Registers will have undefined contents after power-up
• Some registers may be written only once during the life of a TEM power cycle. Writing them a second time will put the TEM in an undefined state.
• Sharon asked whether each and every register should be specified in SchemaConfig files.

q Not the read only registers

q Not the registers that may be written only once per power-up cycle

q Else, yes

• Ric requests that all registers with special needs be identified and documented

q Agreed, tech note forthcoming; TEM Primer to be updated

• CAL (Byron)
• Getting lots of “bad interrupt” messages on the SBC. Think it’s due to a power supply glitch.
• TKR (Luca B.)
• Performed threshold scans
• Did long term tests with good results
• Performed noisy strip map and got some results that Luca would like to investigate further
• Performed tests with a radioactive source and got good results
• Trigger rate is ~500 Hz
• Ready to start converting to Run Control framework
• IFCT (Larry)
• Working with Luca to get charge injection scripts working
• Will add graphs
• Will add test reports
• Toward the end of January, the EM Test setup will move to the LAT assembly building (Bldg 33)
• Will prototype functional tests and write up work instructions
• Then will move on to CAL
• Will integrate test reports
• ACD scheduled for later
